Q. Beats are produced by frequencies $v_{1}and\ v_{2}(v_{1} >_{2})$. The duration of time between two successive maximum or minima is equal to
A) $\frac{1}{v_{1} + v_{2}}$
B) $\frac{2}{v_{1} - v_{2}}$
C) $\frac{2}{v_{1} + v_{2}}$
D) $\frac{1}{v_{1} - v_{2}}$
Explanation
(d) The time-interval between two successive beats
$T = \frac{1}{beat\ freaquency} = \frac{1}{v_{1} - v_{2}}$
